Treatment device for recycling micro-invasive excavation multi-medium subsurface leachate as water for cultivation

Abstract

The invention provides a treatment device for recycling micro-invasive excavation multi-medium subsurface leachate as water for cultivation. The treatment device is characterized in that an auxiliary device and a water distribution device are connected above a water collecting device with a height difference of 3 meters; the structure of the auxiliary device is that compound calcium carbonate particles are filled between two layers of wire entanglements; the water distribution device is composed of a plurality of water distribution tanks arranged in parallel, a composite geo-membrane is laid on the inner periphery of each water distribution tank, the composite geo-membrane is filled with gravel, a water distribution pipe is buried in the gravel and a water hole is formed in the wall of the water distribution pipe; each water distribution tank has a slope; the water collecting device is composed of a plurality of water collecting tanks arranged in parallel and the water collecting tanks are filled with gravel; a water receiving pipe is laid in parallel with the water distribution tanks and a water hole is formed in the wall of the water receiving pipe; the water receiving pipe has a slope; one end of each water distribution pipe in the water distribution device is connected with a water inlet pipe, and the other end of the corresponding water inlet pipe of the water receiving pipe in the water collecting device is connected with a water outlet pipe; the water outlet pipe is connected with a collecting basin, a submersible sewage pump of the collecting basin is connected to a return pipe, and the return pipe is connected to the auxiliary device.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a treatment device for minimally invasive excavation, multi-media underground percolation and back for breeding water. Background technique [0002] With the rapid development of the economy, a large amount of industrial wastewater and domestic sewage are discharged into lakes and reservoirs, causing the pollution of lakes and reservoirs to increase and the number of pathogenic microorganisms to increase. The problem of water purification in ponds around lakes and reservoirs is increasingly caused. Pay attention to. [0003] According to statistics, in 2011, my country's forestry, animal husbandry and fishery consumed 28.38 billion m3 of water. 3 , in Northwest China, water shortage is a prominent problem. Therefore, in order to develop the aquaculture industry in Northwest China, it is necessary to have a simple and low-cost water reuse system to purify the domestic water of reside...

Problems solved by technology

At present, the main methods of water sterilization in aquaculture include physical methods, chemical methods and biological methods, but all sterilization requires centralized pipe network and centralized treatment, which is not suitable for the northwest region with vast land area and scattered population.
